Spatial mapping of HIV testing and antiretroviral therapy initiation uptake among the adolescents and youth in rural KwaZulu-Natal, South Africa
This study investigated the spatial distribution of HIV testing and antiretroviral therapy initiation among adolescents and youth in rural KwaZulu-Natal, South Africa, to inform the optimal allocation of HIV services. The sample included 5,352 participants aged 13-35 years from nested cohort studies within Africa's largest population-based prospective cohorts, with global positioning system data collected for all homesteads. HIV testing prevalenc…

The effect of multi-level HIV prevention interventions on common mental disorders among adolescents and young adults in rural South Africa
This study evaluated the effect of multi-level HIV prevention interventions delivered through DREAMS (Determined, Resilient, Empowered, AIDS-free, Motivated, and Safe) program on common mental disorders (CMD) among adolescents and young adults (AYA) in rural South Africa. We used longitudinal data from two cohorts of AYA aged 13–35 years (N = 2184 for cohort 1 and N = 3067 for cohort 2), recruited between May 2017 and December 2018, with data col…
Alcohol Use and the Pre-exposure Prophylaxis Continuum of Care Among Men in Rural South Africa
Despite freely available oral HIV pre-exposure prophylaxis (PrEP), HIV incidence among young men in South Africa remains high. This study explores the impact of alcohol use on PrEP initiation and continuation among South African men. We performed a secondary data analysis from a trial involving men aged 16-29, randomly selected in KwaZulu-Natal. Participants were referred to sexual health services, and those who were HIV negative and sexually act…
Uptake of multi-level HIV interventions and HIV-related behaviours among young people in rural South Africa
Combination HIV prevention packages have reduced HIV incidence and improved HIV-related outcomes among young people. However, there is limited data on how package components interact to promote HIV-related prevention behaviours. We described the uptake of HIV prevention interventions supported by Determined, Resilient, Empowered, AIDS-free, Motivated and Safe (DREAMS) Partnership and assessed the association between uptake and HIV-related behavio…
Incident pregnancy and mental health among adolescent girls and young women in rural KwaZulu-Natal, South Africa
Pregnancy can place adolescent girls and young women (AGYW) at risk of poor mental health. However, evidence linking youth pregnancy to mental health in resource-limited settings is limited, especially where HIV incidence is high. We analysed a population-representative cohort of AGYW aged 13-25 in rural KwaZulu-Natal to assess how adolescent pregnancy predicts subsequent mental health. Among 1851 respondents, incident pregnancy (self-reported pa…
Adaptation and pre-test of a shortened Stepping Stones and Creating Futures intervention focused on HIV for young men in rural South Africa
Men’s engagement in HIV prevention and treatment is suboptimal, including in South Africa. We sought to address this through adapting an evidence-based intervention, Stepping Stones and Creating Futures (SSCF), to strengthen its HIV content and provide a more scalable (shorter) intervention in rural South Africa. We then conducted a mixed methods pre-test of the intervention among young men aged 18–35 years. To adapt SSCF, we reviewed the current…

Antiretroviral therapy based HIV prevention targeting young women who sell sex
Pre-Exposure Prophylaxis (PrEP) is a potential game-changer for HIV. We used PrEP introduction for Young Women Who Sell Sex (YWSS) in a rural South Africa district to understand community norms and PrEP coverage in YWSS. Between 2017 and 2018, we measured awareness and uptake of PrEP in a representative cohort of 2184 Adolescent Girls and Young Women (AGYW) aged 13-22. We conducted group discussions with young people and community members (19); k…

Local youth were able to use evidence to develop a contextually adapted peer-led intervention to deliver biosocial HIV prevention
Common mental disorders and HIV status in the context of DREAMS among adolescent girls and young women in rural KwaZulu-Natal, South Africa
We found high prevalence of probable CMD among AGYW in rural South Africa, but it was only associated with HIV serostatus when not controlling for HIV acquisition risk factors. Our findings highlight that improving mental health service access for AGYW at high risk for HIV acquisition might protect them. Interventions already reaching AGYW with CMD, such as DREAMS, can be used to deliver mental health services to reduce both CMD and HIV risks. Th…
The Evil of Violence
This article seeks to answer the following question: to what extent does the interpretation of violence as evil contribute – positively, negatively or not at all – to a human rights culture among some 2000 grade 11 students at private (Catholic and Anglican) schools and Afrikaans medium public schools in the Johannesburg/Pretoria region on the basis of surveys conducted in 1995/1996 and 2000/2001? The regression analyses show that on a number of …
